Specification of Letters Patent. Application filed April 3, 1913. Serial No. 758,604.

Patented Feb. 3, 1914:.

To (ZZZ whom it may conegrn: v

Be it known that I, J osEPH E. MCCANLESS, a citizen of the United States, residing at 'Waxa'hachie, in the county of Ellis and have invented certain new Hopples, cation.

My. invention relates to cultivator hopples, and its object is to provide a cultivator hopof which the following is a specifiple so constructed that the lever controlling the same may be angularly adjusted about an axis parallel with the cultivator beams to displace other, and may be also angularly adjusted about an axis transverse of said beams to bring thelever to or from the operator. Such a hopple makes it possible for the operator to swing the controlling lever close to his body so as'to put forth his strength to better effect in adjusting the-cultivator beams to or from each other,'and when the beams are properly spaced, the lever' may be swung gway from the operator soas not to impede A further object of my invention-is to provide a device of the character described that will be strong, durable, simple and efiicient and comparatively easy to construct and also one that will not be likely to get out of working order.

With these and various other objects in view my invention has relation to certain novel 4 features of the construction and operation my invention.

an example of WhlOhlS described in the following specification and illustrated in the accompanying drawing.

i In this drawing, my novel hopple is shown adapted to adjust apair of cultivator beams upon which it is mounted, the cultivator frame-being omitted as'fornnng no part of Referring now more particularly to the drawing, the reference character 1 is ap plied to a pair of cultivator beams provided at their forward ends with the usual pivot heads 2, and serving in the usual manner to i mount plow standards 3. Upon the middle tegral upstanding lugs 5.

stitutes the means for clampingsaid bracket portion of one of the beams, there is clamped a bracket member-4 provided with two in- A U-bolt 6 conupon the correlated beam. beam, at a there is mounted=a bracket Upon the other 7, held in place by a clamping U-bolt andbifurcated at,

said beams to or from each its upper extremity. The function of the,

.bracket 7 will be made clear hereinaften- I The two lugs'5 serve to mount a bolt Qtransverse of the; cultivator beams, which bolt is screw threaded in said lug, and is provided upon its inner end with head 10. head, there is pivoted the lower mg normally parallel with the beams. {Upon the bracket 4, between the lugs'5, there is a bifurcated Between the furcations of said extremity of. a lever'll, the'pivotal axis of said'le'ver-jbecentrallypivoted a horizontal semicircular bolt which pivotally supports the lever 11, said lever and sald rack are adapted to which axis is normally parallel with the cula pivotal support for said bracket- Q- v being formed by one of the arms'of the U Q 9 swing together about the samepivotalaxis,

tivator beams. It is apparent that the lever 11 is also adapted to undergo an angular displacement about the axis established by the bolt 9, said bolt-being rocked during such displacement. The rack 13 will remain stationary when the lever 11 is being subjected to the angular displacement last mentioned. The usual spring pressed plunger is mounted upon the lever 11 to engagebetween any two teeth of the rack 13 and thereby hold the lever 11 in various positions of angular adjustment about the axis formed by the bolt 9. In order to hold the central portion of the rack 13 closely adjacent to the lever 11, so that they must ropoint opposite to the bracket 4.

tate as a unit. about an axis passing through the bolts 14, a small curved bracket 15, is mounted upon the lever'just beneath the central portion of said rack and is made to 'pass beneath said central portion bending up against the outer face said rack must share in any angular displacement to which the lever 11 about an axis through the bolts 14.

16-being bent into a substantially radial relation with the body portion of said rack thereof. Thus I A short space above the rack 13, another. rack 16 transverse with the rack 13 is rigloo is subjected and being pivotally mounted upon the lever 11 as indicated at 16. Upon theother end portion of said rack a screw threaded arm 17 is formed, which arm projects horizontally in the direction of the beam upon which the bracket 7 is mounted. The arm 17 has a threaded engagement with a coliii lar 17 integrally formed upon the lower extremity of a curved bar 18 which projects upwardly at an inclination toward the left hand side of the cultivator. A bolt 19 extending horizont'ally toward the left side of the machine is formed upon the upper end of the bar 18, and has threaded engagement with a pair of lugs 20 formed upon the upper extremity of a bar 21, The last named bar extends downwardly at an inclination to the left hand side of the machineand has i'or1ned upon its lower end a horizontal arm 22, which is received between the furcations of the bracket 7 and is provided with a plurality of bolt holes 23 through any one of 'which may be passed a. pivot bolt mounted in said bracket 7. Upon the lever 11, there is mounted the usual spring pressed plunger to engage between any two teeth of the rack 16 for the purpose of holding said lever adjusted in any position of angular displacement about an axis passing through the bolts 14. i

It is clear from the foregoing description that the lever 11 is adapted to undergo two rack, the lever 11 is restricted from angular displacement about the axis formed by the bolt 9, the lever will be free to swing for- 'wardly or rearwardly, the bolt 9 forming a rocking pivot and the member 18 swinging about its pivoted extremities. \Vhen the lever 11 after having been displaced to a considerable extent'either forwardly or rearwardly of the machine, is subjected to a dis-- placement toward either side of the machine to vary the distance between the beams 1,

r p a latcfiallyacting pressure will come upon an en portion of the rack 14: and will be transmitted to the semicircular bracket 1,2

ca-usingthe same to rock about its pivoted .central point. It is to be understood that when the lever ll-is swung about the pivot formed within the head 10, there will be a relative displacement between the said lever and the rack 16, the latter rocking about its pivoted extremity 16, Accordingas the bolt passing through the holes 23 and the arms 22 is mounted in the outermost or innermost hole, the spaced relation of the plow beams will be greater or less.

The invention is presented as including all such modifications and changes as properly come within the scope of the following claims. o-

\Vhat I claim is:

1. A cultivator hopple comprising a member rotatably mounted upon one of the cultimounted upon said Inember,the pivotal axis of the lever being transverse with the axis of rotation of said member, means correlated with said lever for holding the same adjusted in various positions of angular displacement about the axis of rotation of said member, a toothed rack pivotally mounted upon said lever in a transverse relation with the beams, means mounted upon the lever for engaging said rack to hold the lever in a rigid relation therewith, a connection between said rack and the other cultivator beam, said connection being such that the lever is permitted to swing aboutits pivotal connection with 'said member .only when the rack is free from the said means for engaging the same, and is permitted to swingabout the axis formed by said memher when'freed from the means providedto prevent such displacement.

2. A cultivator hopple, comprlsing a' member rotatably mounted ,upon one of the cultivator beams, the axis of rotation of said member being horizontal and transverse of the correlated beam, a lever ivotally mounted upon said member, the pivotal axis of the lever being transverse with the axis of rotation of said member, means correlated with said lever for holding the same adjusted in various positions of. angular displacement about the axis of rotation of said member, a toothed rack pivotally mounted upon said lever in a transverse relation with the beams, means mounted upon the lever for engaging said rack to hold the lever in a rigid relation therewith, a bar pivotally mounted upon the other cultivator beam, the mounting being such that the said bar may swing transverse of the beam but not longitudinally thereof, and a bar establishing a swinging connection between the upper end of the last named bar and said rack,

said bar being adjusted to swing only toward the front or rear of the machine.

3. A cultivator hopple, comprising a pair axis of the lever being transverse with the axis of rotation of said member, a semicircular bracket centrally pivoted upon the bracket carrying the rotatable membe the pivotal axis being vertical, a semicircular rack having its extremities respectively piv oted upon the extremities of said semicircular bracket, the pivotal axis being nor mally horizontal and parallel with the beams, means holding the central portion of said rack constantly adjacent to the lower portion of the lever, means carried by the lever for engaging said rack to hold the lever in a rigid relation therewith, a toothed rack pivotally mounted upon the lever above the first n me rack and in a transverse relation with the beams, means mounted upon the ever for engaging said rack to hold the lever ina rigid relation therewith, aeonnection between said rack and the other cultivator beam, said connection being such that the lever is permitted to swing about its pivotal connection with said member only when the rack is free from the said means for engaging the same, and is permitted to swing about the axis formed by said member, when freed from the means provided to prevent such displacement.

In testimony whereof I have signed my name to this specification in the presence of 30 two subscribing witnesses.
